SOLDERING DEVICE.

SPECIFICATION forming part of Letters Patent No. 693,500, dated February 18, 1 902. Application filed AprilZ'l, 1901. Serial No. 57,768. (No model.)

To all whom it may concern:

Be it known that we, NVILLIAM E. CRANE and EDWARD T. HOLTON, citizens of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented a new and useful Soldering Device, of which the following is a specification.

This invention relates generally to soldering-irons, and more particularly to a combined soldering-iron and solder, the object be ing to provide a hydrocarbon-burner in conjunction with the soldering-iron, so that the iron proper is always kept at the proper temperature for soldering purposes. 7

Another object of the invention is to provide a soldering-iron of this character which can be easily manipulated; and with these objects in view the invention consists, essentially, in connecting a hydrocarbon-burner with a soldering-iron and in pivotally connecting the supply-pipe to a reservoir mounted upon the rollers.

The invention consists also in certain details of construction and novelties of combination, all of which will be fully described hereinafter, and pointed out in the claims.

In the drawings forming part of this specification, Figure 1 is a perspective View of a soldering-iron constructed in accordance with our invention. Fig. 2 is a longitudinal sectional View taken through the iron proper. Fig. 3 is a detail perspective View showing the end of the burner and nipple. Fig. 4 is a detail perspective view of the collar arranged upon the end of the burner-pipe. Fig. 5 is a detail View showing the sleeve surrounding the hollow portion of the iron and connecting said iron to the collar; and Fig. 6 is a perspective View of the soldering-iron or copper, as it is usually termed by the trade.

In carrying out our invention we employ a soldering-iron or copper A, the forward end of which is constructed the same as irons or coppers now in use. This head or end, however, has a rearwardlyextending hollow portion B,-the bottom of which is perforated, as shown B. A sleeve 0 is fitted upon the rear shoulder of the head A and serves to connect the iron with a collar D by means of a setscrew D. The sleeve C entirely surrounds the hollow or tubular portion of the soldering-iron and has a series of perforations 0, produced in the bottom, and has a single opening C produced in the top to serve as a vent, and this openingis protected by means of a hood C The collar D has an upwardly-extcnding lug or projection D into which is threaded the handle E. The collar is also threaded ceutrally, as shown at D to receive the threaded end of the burner-pipe F, and a perforated nipple G is inserted in the forward end of the burner-pipe and projects a slight distance into the hollow or tubular portion of the soldering-iron. An opening D is also produced in the collar D directly below the threaded aperture D the purpose of which is to permit the return-flame to heat the adjacent portion of the pipe F, and thereby vaporize the fuel fed to the burner ornipple. Air is supplied through the small openings D arranged adjacent to the central opening D upon either side of the same and slightly above the opening D Any suitable construction of regulating and forcing means may be employed in connection with the burner, and inasmuch as this mechanism forms no part of our invention it is not necessary to describe the same. The hydrocarbon fuel is contained within the tank H, having the usual filling-cap and forcing-pu mp connected therewith. The oil-supply pipe I has a swivel or pivotal connection with the tank, as shown at I, so that the iron can be manipulated by means of the handle without interfering with the position of the tank H,'and in order that the tool may be specially fitted for soldering roof-sheets we mount the tank H upon caster-rollers H, so that the tank can be moved along easily as the soldering progresses.

In operation it is understood that when the burner is lighted and burning within the hollow or tubular portion of the iron the head or soldering portion will of course be rapidly heated to the proper temperature and maintained at such temperature, the heat not only circulating Within the tubular or hollow portion, but entirely around the same, owing to the fact that said portion B is surrounded by the sleeve 0, Which permits the flame to play entirely around the hollow or tubular portion B. The opening Dpermits a returning flame,

and consequently vaporizes the fuel before it passes into the burner proper or nipple.

It will thus be seen that We provide a simple construction of solderingiron and heater which can be easily moved about during the soldering operation and carrying with it the oil-supply tank.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a device of the kind described, the combination with a soldering-iron having a hollow or tubular extension-perforated as described, a sleeve surrounding the said hollow or tubular portion, a collar having a central opening, and a return-flame opening beneath the said central opening, the oil-pipe fitted into the central opening and having a perforated burner or nipple fitted therein, and a handle attached to the collar, substantially as set forth.

2. In a device of the kind described, the

combination with a soldering-iron having the soldering-iron head and'the hollow or tubular extension, the collar having a centrallythreaded opening, the return-flame opening, and the air-supply openings produced therein, said collar also having an upwardly-projecting lug or extension, the handle attached to the said lug and extension, the oil or vapor pipe fitted in the central threaded opening, the perforated burner or nipple fitted in the end of the said pipe and projecting into the hollow or-tnbular portion of the iron, and the sleeve connecting the head of the iron and the collar, said sleeve having perforations in the bottom, a vent in the top and the protecting-hood arranged above said vent, substantially as and for the purpose described.
